摘要： A driving device for a display apparatus and a driving method for the same are provided. In the driving device, scanning signals and data signals having a plurality of periodical inactive portions in one frame are applied to respective display dots. In the inactive term, a fixed voltage is applied to each of the display dots. The signal applied to the display dot is divided into small terms by the inactive portions, resulting in higher frequency components in the voltage signal applied to the display dot. As a result, the frequency components of the driving signal applied to the display dot are averaged. Further, a complete orthogonal function having 2 r base function series is used, and a desired display data is completely reproduced on the display apparatus by an arithmetic process assuming auxiliary data in accordance with the number of the scanning electrodes.

摘要： In a projection type liquid crystal display device wherein the rotation direction of the twist of the liquid crystal molecules of the liquid crystal layer (11) in a first liquid crystal panel (10) is opposite to that of the twist of the liquid crystal molecules of the liquid crystal layer (21) in a second liquid crystal panel (20) adjacent to said first liquid crystal panel; the orientation of the liquid crystal molecules of a portion of the liquid crystal layer in the first panel (10) in the vicinity of the liquid crystal layer in the second panel (20) is intersected at right angles to that of a portion of the liquid crystal layer (21) in the second panel (20) in the vicinity of the liquid crystal layer (11) in the first panel (10); and the electrode lines (15) placed in a parallel manner in the first panel (10) are not superposed in the direction of light transmission on the electrode lines (25) placed in a parallel manner in the second panel (20), whereby the display capacity can be increased without increasing the number of time-sharing and a display of high resolution and excellent contrast can be achieved.

摘要： A display device, which takes a specified period to rewrite the picture elements in one horizontal scanning period, comprises M pcs. of scanning lines divided into a plurality of groups each containing K pcs. of scanning lines (K > 1, M > 1, K, M: positive integers) and elements for supplying scanning signals to the M pcs. of scanning lines to rewrite an image. The scanning signal-supplying elements output scanning signal to the first scanning line of each group in the first frame, to the second scanning line of each group in the second frame, and to the Kth scanning line of each group in the Kth frame so that the M pcs. of scan­ning lines are rewritten by K times of scanning.
